PICTURE-FRAME.

SPECIFICATION forming part of Letters Patent No. 226,654, dated April20, 1880, i

' Application filed December 27,-1879. v

To all whom it may concern Be it known that 1, WILLIAM LIND EcK- MAN, ofthe city, county, and State of New York, have invented certain new anduseful Improvements in Picture-Frames, of which I declare the followingspecification, when taken in connection with the accompanying drawings,to be such a full, clear, and exact description as will enable othersskilled in the art to make the same.

In said drawings, Figure 1 represents the improved frame by a plan view.Fig. 2 is an enlarged cross-section of the same, taken on the line as ofFig. l, and showing a picture as mounted in said frame. Fig. 3 is anenlarged cross-section, showing a modification of the frame. Fig. 4 is aperspective view of a portion of one of the parts of the frame.

The object of my invention is the production of an article which, whilepossessing all the beneficial qualities of the materials now in use forthe purposesuch as strength, lightness, capacity to receive a smoothsurface of high finish and ornamentationmay be constructed at much lesscost and sold at a considerably lower price.

The said invention consists in an improved picture-frame consisting ofsides, to the face of which is secured the picture-mount and to the backof which is secured a back board, whereby all twisting and warping ofthe frame is prevented and the picture-receivin g surface is sustainedin a level and even position, and, in combination therewith, asupporting-piece that is interposed between the picture-mount and theback-board.

In carrying out my invention I construct the parts of the frame of anysuitable material, preferably using lengths of material, by superposinga suitable number of strips of mill-board, veneer, or other likematerial, as the strips marked 1, which are united together by anysuitable cement applied to their contact-surfaces, which strips, whenpiled to constitute the desired thickness, are snugly consolidated inany suitable press, where they remain-until the cement uniting thembecomes dry and a compact and solid piece, as A, is obtained. Inconstructing this piece A the various strips 1 composing it may vary inwidth and length, as is shown in Fig.4, thus enabling the economical useof material and rendering it possible to reach the minimum cost ofproduction. This mode of structure also provides for the production ofcontinuous straight lengths and the making of circular or irregularforms having continuous bodies. Such pieces as A may then be planed orotherwise cut into any desired conformation, as the bevel 2, the ogce 3,or other molding, and may be gilded, stained, or otherwise ornamented,and may or not be channeled, as at 4, to receive ornamental fabrics ormoldings, as 5, and may or not be rabbeted, as at 6, to receive the pic-.ture-mount B, and provided or not, in addition thereto, with a rabbetto receive a coveringplate of glass.

The picture-mount B may be cemented in the rabbet 6, as in Fig. 3, orupon the face of the sides A of the frame, as in Fig. 2, in eitherposition uniting the upper portions of the frame rigidly together.

In order to prevent warping, due to climatic influences, to change inthe weather, or subjection to moisture, the frame is also provided witha back board, 0, consisting of a board attached at the back of theframe-sides, so as to unite and tie the same together at that point. Thepicture-mount thus forms a brace upon one face, and theback-board formsa brace upon the opposite face, whereby twisting or warping is preventedand the parts are held in their true position.

A frame thus composed out of any material may be made of very greatthickness, and, while possessing great strength, will remaincomparatively light. It is readily adapted to have a picture securedupon the surface of its mount B, to which the same may be attached bycementing, in the usual way, and its structure is such that it willsustain exposure and use without twisting or warping, thus retaining itsoriginal or perfect form.

. The circular or the irregular forms given to the sides of the framemay be gilded or otherwise ornamented, and the exposed parts may to bearagainst both the back-board G and the picture-mount and hold the latterup to a proper level. In large sizes two or more of thesebody-supporting pieces D-may be provided,and, whether one or more areused, they may be held in place by attachments to the picture-mount B,or to the back-board O, or to the sides A of the frame.

When a glass covering-plate is to be used the same may be secured inplace in any appropriate manner, as by an overlapping strip cementedover its edge and united to the sides of the frame.

What I claim is 1. As a new article of manufacture, a picture-frameconsisting of sides A, to the front of which is permanently secured thecard mount B, and to the back of which is secured a back-board, 0,whereby warping and twisting is prevented, substantially as described.

2. In a picture-frame, the combination, with the sides A, picture-mountB, and back-board O, of the body-supporting piece D, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
